The SCARECROW Gene Regulates an Asymmetric Cell Division That Is Essential for Generating the Radial Organization of the Arabidopsis Root
Laura Di Laurenzio,Joanna Wysocka-Diller,Jocelyn E. Malamy,Leonard Pysh,Yrjö Helariutta,Glenn Freshour,Michael G. Hahn,Kenneth A. Feldmann,Philip N. Benfey +8 more
TL;DR: A key role for SCR is indicated in regulating the radial organization of the root in the Arabidopsis root meristem thanks to the deduced amino acid sequence of SCARECROW.

Disrupting Two Arabidopsis thaliana Xylosyltransferase Genes Results in Plants Deficient in Xyloglucan, a Major Primary Cell Wall Component
David Cavalier,Olivier Lerouxel,Lutz Neumetzler,Kazuchika Yamauchi,Antje Reinecke,Glenn Freshour,Olga A. Zabotina,Michael G. Hahn,Ingo Burgert,Markus Pauly,Markus Pauly,Natasha V. Raikhel,Kenneth Keegstra +12 more
TL;DR: It is concluded that XXT1 and XXT2 encode xylosyltransferases that are required for xyloglucan biosynthesis in vivo and this results in significant changes in the mechanical properties of these plants.
A Comprehensive Toolkit of Plant Cell Wall Glycan-Directed Monoclonal Antibodies
Sivakumar Pattathil,Utku Avci,David Baldwin,Alton G. Swennes,Janelle A. McGill,Zoë A. Popper,Tracey Bootten,Anathea Albert,Ruth H. Davis,Chakravarthy Chennareddy,Ruihua Dong,Beth O'Shea,Ray Rossi,Christine Leoff,Glenn Freshour,Rajesh Narra,Malcolm A. O'Neil,William S. York,Michael G. Hahn +18 more
TL;DR: The epitopes recognized by many of the mAbs in the toolkit, particularly those recognizing arabinose- and/or galactose-containing structures, are present on more than one glycan class, consistent with the known structural diversity and complexity of plant cell wall glycans.

The Arabidopsis irregular xylem8 Mutant Is Deficient in Glucuronoxylan and Homogalacturonan, Which Are Essential for Secondary Cell Wall Integrity
Staffan Persson,Kerry Hosmer Caffall,Glenn Freshour,Matthew T. Hilley,Stefan Bauer,Patricia Poindexter,Michael G. Hahn,Debra Mohnen,Chris Somerville,Chris Somerville +9 more
TL;DR: The data presented show thatIRX8 affects the level of glucuronoxylan and homogalacturonan in higher plants and that IRX8 provides an important link between the xylan polymer and the secondary cell wall matrix and directly affects secondary cell walls integrity.
Developmental and Tissue-Specific Structural Alterations of the Cell-Wall Polysaccharides of Arabidopsis thaliana Roots.
TL;DR: It is striking that these three polysaccharide epitopes are not uniformly distributed within the walls of a given cell, nor are these epitopes distributed equally across the two walls laid down by adjacent cells.
